LOOiVI-TEMPLE.

SPECIFICATION forming part of Letters Patent N 0. 641,631, dated January16, 1900.

Application filed July 21', 1899.

To all whom it may concern:

Be it known that I, NICHOLAS I. ALLEN, of Everett, county of Middlesex,State of Massachusetts, have invented an Improvement in Loom-Temples,ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters and numerals on the drawingsrepresenting like parts. 7

This invention relates to temples forlooms; and it has for its objectthe production of a temple which may be quickly and easily removed fromits stand or plate in which the shank of the temple-head normallyreciprocates, locking means holding the parts securely in operativeposition under normal conditions.

Figure 1 is a top or plan view of a loom temple embodying one form of myinvention, the cap being partially broken out to show the tooth of theroll. Fig. 2 is aside elevation of the temple shown in Fig. 1, the headand shank being shown in dotted-line position as ready to be removedfrom or inserted into operative position on the stand. Fig. 3 is alongitudinal sectional detail of the stand, taken on the lineman, Fig.1.Fig. 4 is a transverse sectional detail of the stand on the line 00 m,Fig. 3, looking to the right. Fig. 5 is a longitudinal sectional view ofthe cap, pod, and temple-roll on thelineoc, Fig. 1. Fig. 6 is a sideelevation of the roll-body, showing the seats for the toothed blades;and Fig. 7 is a side elevation of one of the toothed blades detached.

I have herein shown the stand A provided with a longitudinal slot a toreceive the usual attaching-bolt by which the stand is secured to thebreast-beam of the loom, and the stand is herein shown as provided atits inner end with an upturned transverse ear a, said ear having a holea therein, the bottom 3 of which is beveled rearwardly and downward, asclearly shown in Fig. 3, for a purpose to be described. The outer end ofthe stand is provided with two upturned and parallel ears a extendedlongitudinally of the stand and provided on their inner faces withundercut grooves or guideways a (see Figs. 3 and 4,)

Serial No. 724,602. (No model.)

extended from the rear ends of the ears toward the front of the stand toform shoulders or stops Q The temple-head has an attached podB and shankB,adapted to slide longitudinally upon the stand under normalconditions, the shank being provided with lateral projections or lugs11, adapted to enter and slide in the guideways a when the temple is inoperative condition, the rear end of the shank at such time extendingthrough the hole a in the ear a and being guided thereby as thetemple-head and shank are reciprocated, a strong spring S being hereinshown as coiled around the shank between the projections and the car a,the cars a on the stand being far enough apart to admit the front end ofthe spring between them, as shown in Fig. 1, the spring normallymaintaining the temple-head pressed outward with the projections 19against the stop-shoulders a.

Ordinarily the guideways a prevent the shank from lifting, whilepermitting it to reciprocate; but when it is desired to remove thetemple from the stand the shank is retracted till the projections 17 arefree of the guideways, and then the shank is tipped up, as indotted-line position, Fig. 2, the beveled bottom of thehole a permittingsuch tipping of the shank, and the latter can then be withdrawn bodilyfrom the ear a. The reverse operation readily and quickly effects the assembling of the temple and stand in operative position.

The guideways on the one cooperating with the lateral projections on theother form looking means to maintain the stand and temple connectedtogether under ordinary circumstances.

The entire separation of the head and stand is very desirable attimes-as, for instance, when the operative finds it necessary to takeout one or more picks.

Referring to Fig. 3, it will be noticed that the rear end walls of theears a are cutaway or notched to leave shoulders a at the entrances ofand above the guideways a and when it is desired to maintain the templeretracted without removing it altogether from the stand the head ispushed back until the projections 11 rest against the shoulders at, theshank being slightly tipped up for the purpose.

I have herein shown the pod B as provided with means for pressing thecloth firmly against the teeth of the roll, such means being hereinrepresented as a yielding rib b extended longitudinally of the podadjacent and above the edge thereof, the rib being preferably made of apiece of flattened wire bent at its ends transversely, as at If, andcurved to conform to the interior of the pod, to which itis secured inany suitable manner, as by soldering.

I have herein shown a rib located adjacent each longitudinal edge of thepod to engage the cloth ateach side of the roll, the ribs acting to holdthe cloth firmly against the teeth, yet possessing sufficient elasticityto yield slightly when necessary.

The upturned end I) of the pod (see Fig. 5) has a threaded hole I) toreceive a screwplug 0, having a suitable polygonal head 4, a woodenjournal c being secured to the plug in any usual manner, as by drivingit into a hole in the plug and extending the length of the roll to bedescribed, the body of the latter being made of metal and rotating onthe wooden journal, which I prefer to saturate with oil, tallow,or someotherantifriction compound to reduce the friction to a minimum.

The cap D may be of any usual construction, its downturned end (1 havinga hole d therein to receive the plug, the head 4 of the latterserving topress the end of the cap firmly against the end of the pod when the plugis screwed home, to thereby hold the cap in place. Manifestly thewithdrawal of the screwplng will release the cap and the roll can beinstantly removed from the pod.

The roll itself comprises a body portion and detachable toothedblades,which are mounted on the body in grooves or seats extended fromone to the other end of the body.

Referring to Figs. 5 and 6, the metallic body is herein shown asannularly grooved atf to leave end and central cylindrical portions f,the body being reduced at its ends, as at f and extcriorly threaded, thebody being centrally bored to receive the journal 0 The annular groovesfare made to reduce the weight of the body, and they leave end andmiddle supports for the toothed blades to be described, said largerportions f having formed therein, as by saw-cuts, suitable grooves orseats f extended in the direction of the length of the body, but at aslight angle to its longitudinal axis, to give the proper spiralarrangement to the teeth, and into each groove or seat is inserted atoothed blade {1, which I have herein shown as reduced at its ends, asat g, to project beyond the main body portion when the blades are inplace.

Capsf, Figs. land 5, countersunk at their inner ends, as at f to embracethe reduced ends of the blades, are provided with threaded holes toscrew onto the threaded extensions f of the body of the roll, to therebyfirmly hold the blades securely in place on the body.

Should one or more teeth become bent or broken, the particular blade canbe readily removed and a new blade inserted.

By having blades with teeth of various degrees of evenness it will beobvious that the same body can be utilized to present a temple-rollhaving fine or coarse teeth, according to the class of work to beperformed. This mode of constructing the toothed roll obviates theneeessity for inserting very accurately the separate teeth or points inthe body of the roll, as has been heretofore the practice.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. In a loom-te1nple, a temple-head having a shank provided with lateralprojections, a stand having parallel undercut guideways open at theirrear ends to receive said projections, stops at the front ends of saidguideways, and a transverse car at the inner end of the stand, aperturedto receive the shank.

2. In a lo01n-temple,a stand havinga shankguide at its outer end,provided with undercut, parallel ways, a transverse car at its inner endhaving an aperture with a rearwardly and downwardly beveled bottom, anda temple-head provided with a shank, the latter having lateralprojections normally retained in place by the parallel ways of saidguide and by the apertnred ear, the beveled bottom of the latterpermitting the shank to be tipped to withdraw the shank from or toinsert it in its guide on the stand.

3. In a loom-temple, atemple-head having a shank provided with lateralprojections, a stand having parallel upturned ears provided on theirinner faces with undercut grooves to receive said projections, anapertured,transverse ear on the stand, to receive the shank, and stopsat the rear ends of the parallel ears, to engage the projections on theshank and maintain the temple-head retracted.

In testimony whereof I have signed my name to this specification in thepresence of two subseribin g witnesses.

NICHOLAS I. ALLEN.
